Gamma spectroscopy is an analytic technique that identifies isotopes through gamma rays. Currently, widely used in several science fields, for instance, the study of hydrodynamics soils and other applications. Considering development computers, it has been developed Monte-Carlo simulation packages, order to estimate response detectors. This work aims develop a GEANT4 application full energy pea...

The Cryogenic Dark Matter Search (CDMS) is an experiment to directly detect dark matter, a mysterious substance that makes up the majority of the matter content in the Universe and has so far only been observed due to its gravitational effects. CDMS uses high-purity Ge (HPGe) crystals as detectors for dark matter in the form of weakly interacting massive particles (WIMP). In order to reduce sys...

Abstract A standard procedure for characterizing the high-purity germanium detector (HPGe), manufactured by Canberra Industries Inc [1], is performed directly company using patented methods. However, usually expensive and must be repeated because characteristics of HPGe crystal change over time. In this work, principles a technique are developed use in obtaining optimizing based on cost-effecti...

This document contains a proposal of the BEPC-II collider beam energy calibration system (IHEP, Beijing). The system is based on Compton backscattering of carbon dioxide laser radiation, producing a beam of high energy photons. Their energy spectrum is then accurately measured by HPGe detector. The high-energy spectrum edge will allow to determine the average electron or positron beam energy ε ...

One of the goals of hypernuclear physics is to study the properties of baryon-baryon interaction including the strangeness contribution. Double hypernuclei can provide information about the ΛΛ interaction in addition to the hyperon-hyperon and hyperon-nucleus one. A new technique for producing double hypernuclei using antiprotons is foreseen in the PANDA experiment at FAIR. Gamma ray spectrosco...
